I use it for chat apps, phone calls (usually via chat apps), and occasionally wandering around Imgur when it would be socially awkward to not be on my phone.
The rest of the time I've come to appreciate being present in the moment.
So yeah, I'm looking at the new generation of Linux phones with interest. If I can run the chat apps in a browser OK, then I think it might work for me.
Related, if in a group, everybody else disengages to be engrossed in their phone, it can be helpful to do the same if one does not want to demonstrate a vulnerable dependency on the generosity of their attention.
A lot of awkwardness comes down to self-perception of vulnerability.
Though if everyone else is on their phone, and the crowd is large enough, I find it fascinating to people-watch.
I do find it useful to sometimes be absorbed in my phone and not aware of what's going on around me. Or at least to have that impression.
